  • The standard WCBS has a braking power up to 263kW. 
  • B10 life is greater than 1,000,000 km. 
  • Better economy

  • The speed that can achieve minimum fuel consumption covers the whole working speed range. 
  • The Weichai ECU control system improves driver’s shift schedule and thus reduces fuel consumption. 
  • The engine speed matching point for the same vehicle speed is lowered by 200r/min, reducing frictional work and fuel consumption. 
  • High configuration

  • The lightweight and modular design of the engine significantly reduces the weight of the engine and reduces the number of peripheral parts.
